My project loaded Cesium World Terrain, Bing Maps Aerial, and 400 Cubes. When I was running, browsing and moving scene content got stuck; My machine has 128g of memory, 3T of disk, and Windows 10 operating system. When running the project, the memory has just been consumed to 20g; Why does Unity get stuck when loading multiple cubes? Are there any optimization solutions

I’m not sure. Are these cubes just static meshes? Or do you mean a 3D Tiles tileset that is just a cube? If it’s the latter, 400 3D Tiles tilesets is an unusually large number that I’ve certainly never tested myself, though it’s not obvious why it would be a problem.
